Chapter 12 Expansion Control
12.1.2 Setting the required parameters for speed-torque control
The "Positioning parameters" must be set to carry out speed-torque control.
The following table shows the setting items of the required parameters for carrying out
speed-torque control. When only speed-torque control will be carried out, no
parameters other than those shown below need to be set. (Use the initial values or
setting values within a range where no error occurs for trouble-free operation.)
Setting item Setting requirement
Pr.1
Unit setting
Pr.2
Number of pulses per rotation (AP)
Pr.3
Movement amount per rotation (AL)
Pr.4
Unit magnification (AM)
Pr.8
Speed limit value
Pr.12
Software stroke limit upper limit value
Pr.13
Software stroke limit lower limit value
Pr.14
Software stroke limit selection
Pr.22
Input signal logic selection
Pr.82
Forced stop valid/invalid selection
Pr.83
Speed control 10 x multiplier setting for degree axis
Positioning parameters
Pr.90
Operation setting for speed-torque control mode
: Setting always required.
: Set according to requirements (Leave set to the initial value when not used.)
REMARK
•
Positioning parameter settings work in common for all control using the QD77MS.
When carrying out other control ("major positioning control", "high-level positioning
control", "OPR control"), the respective setting items must also be matched and
set.
•
Parameters are set for each axis.
•
Refer to Chapter 5 "Data Used for Positioning Control" for setting details.
